NME uses several techniques as selling points to attract readers and boost sales: 1) Words like "unseen" and promises of new, exciting content entice viewers to buy more issues for additional information. 2) Bright colors are used on the cover and pages to grab attention as viewers are more likely to purchase if the magazine stands out visually. 3) Teasing previews with words like "inside" give a taste of articles but imply more details are within, encouraging further reading or purchase.
